Any pics of it installed on the car, I'd like to see how you routed them, are they dumped at the axle or do they go over the axle and out the back?

I have 12 inch 2.5 and they makes a HUGE difference on my car. Not quite by any means ,but still a noticeable difference. The first time I drove my car home it was just open header...I knocked a picture off the wall. Now, I just **** the neighborhood off when I come home.

I used to have the longer version of those on my car. and it cut the noise way down. I didn't like it and took them off and now i just run headers, x-pipe, then dumped. That was several years ago. Now that I'm a lil older and the car is little to loud for my taste.

Nice, I have 2 of these under my car. They're pretty loud but not as bad as open exhaust. They sound nothing like "Flowmasters"!
